Scanning tunnelling electron microscopy

Sophisticated techniques, such as scanning tunneling electron microscopy, provide visual evidence for the structure of atoms and molecules. The planar nature of graphite, a commonly used lubricant. Is shown here the peaks are Images of carbon atoms. [Pg.40]

Biologically synthesized nanomateriais may be characterized using the same instrumental techniques as for traditionally synthesized nanomateriais. The most commonly used methods for the analysis of precious metal nanopartides indude high-resolution transmission electron microscopy (HRTEM), TEM, SEM, scanning tunneling electron microscopy (STEM), XRD, electron diffraction (ED) or SAED and XAS, which incorporates extended X-ray absorption fine structure (EXAFS) and X-ray absorption near edge structure (XANES) [7, 8]. [Pg.465]

A different technology used by third-generation sequencers is the one developed by companies such as Halcyon or ZS Genetics that uses a rapid-scan tunneling electron microscope to read the DNA chain directly (44). DNA bases have to be labeled with heavy atoms to make them visible under the electron microscopy. Each nucleotide is tagged with a characteristic heavy label so that they can be distinguished in the transmission electron micrograph. [Pg.61]

Microscopy which includes optical, scanning, transmission and tunnelling electron microscopy. [Pg.618]
